Abstract

PURPOSE:To reduce load of a CPU, by troubleshooting earlier and making efficient the discrimination of normality/abnormity of storage area with less access frequency, through the detection of auxiliary storage device per a specified period. CONSTITUTION:All areas A of an auxiliary storage device 2 consisting of protective area D and non-protective area E are split into blocks B1-Bn, and check patterns P1-Pn are written in areas C1-Cn of each block. Readout of the pattern P1 is made from a CPU1 to the device 2 at a specified period, it is compared with a reference pattern stored in a main storage device 3, and when the readout is normal and the result of comparison is equal, the normality of the area D is discriminated. Similarly, the patterns P2-Pn are read out, and when the readout is normal and the result of comparison is equal, patterns Q2-Qn are written in the areas C2-Cn and the comparison is repeated. At the check of the regions D, E, when the readout is abnormal, an alarm is outputted to an operation console 6.
